With an extra day to prepare for the next game in their best-of-7 series against the Canadiens, the Bruins – with the exception of a few players who came to TD Garden to fulfill media obligations, plus those who didn’t play on Saturday -- got to take Sunday off. The B’s have a practice scheduled for Monday morning at the Garden, and will then depart for Games 3 (Tuesday) and 4 (Thursday) in Montreal.

Noteworthy, however, was a two-sentence statement from general manager Peter Chiarelli regarding surgery for injured defenseman Adam McQuaid, and a response from coach Claude Julien’s meeting with reporters about injured winger Chris Kelly.

- McQuaid hasn’t played since Jan. 19, when he injured the same quad muscle in his left leg for the third time. He was seen Saturday using crutches, and shortly after Julien was asked about that on Sunday, the team issued the following statement from Chiarelli:

“McQuaid underwent successful arthroscopic surgery on Thursday, May 1 on his right ankle. His expected recovery time is eight weeks.”

That puts McQuaid out until next season, although the quad injury might have done that anyway. He sustained that injury for the first time on Nov. 9, in a game against Toronto.

McQuaid had been skating with other injured Bruins as recently as their first-round series against Detroit. It’s not known if he injured the ankle during that comeback attempt, or if it’s somehow related to the quad injury.

- Julien, who has pretty much stopped discussing injuries since the end of the regular season, said this about Kelly, who has now been out for almost four weeks with a back injury sustained April 8 at Minnesota. He has not been seen on skates since then.

“Every day’s a better day for him. That’s basically all I can tell you.”
